Japanese Barberry is a problem if it gets into our woodlands and pastures. Just as bad as wild rose.

I would carpet the Earth with Karl Foerster Grass if I could. Love the stuff!

Classification in Wisconsin: Restricted (this restriction only applies to the parent type, the variety atropurpurea, the hybrid of B. thunbergii x B. Koreana, and the following cultivars. Berberis thunbergii cultivars: Sparkle, ‘Anderson’ Lustre Green™, Erecta, ‘Bailgreen’ Jade Carousel®, Angel Wings, Painter’s Palette, Inermis (‘Thornless’), Pow Wow, Golden Ring, Kelleriis, Kobold, ‘JN Variegated’ Stardust™ and Antares. Variety atropurpurea cultivars: Marshall Upright (‘Erecta’), Crimson Velvet, ‘Bailtwo’ Burgundy Carousel®, Red Rocket, ‘Monomb’ Cherry Bomb™, ‘Bailone’ Ruby Carousel®, JN Redleaf, Rose Glow and Silver Mile. Hybrid of B. thunbergii x B. koreana cultivars: Tara and ‘Bailsel’ Golden Carousel®)

So, lots of nursery growers losing lots of money and having to destroy stock.

Wow! I recognize Red Rocket, and that’s the only one I’m familiar with. Wow!

I will research. Thanks so much!

So, here’s what I learned about the invasive Barberry; some are sterile by nature. Same with Nandina: certain varieties are sterile. (Maybe that’s why certain Barberry is used here in Georgia.) I was going to use Red Rocket, but think I’ll go with Orange Rocket.

Good discussion, Diana.

You may find this interesting: Barberry is not invasive here in the south due to our climate, and our soil.

Japanese Honeysuckle, Seabuckthorn, and Bradford pear are also invasive and problmatic.

(I am in a constant battle of grubbing the Honeysuckle on my property.)
